Forgeries of this kind first appeared on the market in 2011. Most are smaller in diameter and heavier in weight than genuine ones.

Agree. I've see hundreds of such on sale online + offline. 10+ different die varieties are known to have been forged. A disaster for beginners.

Corrosion on this example looks very realistic.

Size and weight differences are perhaps the most obvious criteria. Genuine Da-Ding Tong-Bao of the *same* die variety tend to have *very* low size deviations (i.e. less than ±0.3mm acccording to my observations). I would recommend you to refer to the discussion of "Rev. You"'s sizes in http://www.zeno.ru/showphoto.php?photo=26230 .
